So the AX relay is made up of two relays. There is a lock relay that energizes and releases the main relay. Does the lock relay energize? Make sure that happens first. If it does energize but doesn't release the AX relay, one or both of the relays may be out of adjustment. There are screws to loosen the relays so they can be moved. Be forewarned, these relays are an absolute PITA to get just right. After several days when you get it working. Never, ever touch them again. Seriously.
